Red Lion RLCB10-230 1-HP VMC Control Box
The Red Lion RLCB10-230 is designed for 1 HP, 230-volt, three-wire, single-phase deep well submersible pumps. It carries a NEMA Encl. 3 rating for indoor/outdoor use and UL listing in the USA and Canada. It includes four knockouts of 7/8 inch and three knockouts of 1-1/8 inch, plus a drain hole and two mounting holes. Best for smaller to mid-size wells where weather resistance and straightforward installation matter. A potential limitation is the fixed knockout configuration, which may require planning for certain wiring layouts.
Red Lion RLCB15-230 1.5-HP VMC Control Box
The RLCB15-230 supports 1.5 HP, 230 V, three-wire, single-phase deep well submersible pumps. It is also rated for indoor/outdoor use with NEMA Encl. 3 protection and UL listings. It includes diverse conduit knockout sizes (1/2″, 3/4″, 1″, and 1-1/4″) and three mounting holes for flexible installation. This model suits higher-power applications or upgrading from a smaller box. A potential limitation is the larger footprint compared to smaller horsepower models.
Red Lion RLCB05-230 1/2-HP VMC Control Box
The RLCB05-230 is tailored for 1/2 HP, 230 V, three-wire, single-phase deep well pumps. It features a NEMA Encl. 3 rating for indoor/outdoor use and UL listing. It includes four knockouts of 7/8 inch and three knockouts of 1-1/8 inch, plus a drain hole and two mounting holes. Best for compact, cost-conscious installations. A caveat is that it offers lower horsepower capacity, which may not suit larger wells or higher-flow requirements.
Red Lion RLCB07-230 3/4-HP VMC Control Box
The RLCB07-230 provides 3/4 HP, 230 V, three-wire, single-phase operation with indoor/outdoor capability under NEMA Encl. 3. It includes four 7/8-inch knockouts, three 1-1/8-inch knockouts, a drain hole, and two mounting holes. It targets mid-range applications where a balance of power and size is needed. A noted limitation is similar to other 230V models: if conduit planning requires different knockout sizes, extra wiring work may be needed.
Briidea Well Pump Control Box (1.5 HP)
The Briidea control box targets a 1.5 HP, 230 V, three-wire, single-phase deep well submersible pump with weatherproof construction and five knockout openings to connect from multiple directions. It highlights overload and thermal protection to prevent short circuits and protect the pump’s operation. It offers easy installation and cost-saving maintenance by enabling component replacement without pulling the pump. A caution is that detailed electrical compatibility beyond the listed specs should be verified before installation.
Buying Guide
- What horsepower do you need? Match the control box to your pump’s horsepower (0.5–1.5 HP in the selections above) to ensure proper motor protection and electrical loading.
- Indoor vs outdoor use: If the installation is exposed to weather, choose models with NEMA Encl. 3 protection and UL listings for reliable outdoor performance.
- Conduit and knockouts: Check the available knockout sizes and count to fit your wiring plan. Some boxes offer multiple options for flexible conduit routing.
- Protection features: Look for overload and thermal protection to mitigate failures and extend pump life. Verify what the relay and protective components cover.
- Maintenance and replacement: Consider models that allow easy component replacement without removing the pump, reducing maintenance time and cost.
